In assessing whether students are understanding the mathematical concepts in a picture book it is helpful to pause throughout the story and ask probing questions. For instance, in "Dozens of Doughnuts" by Carrie Finison and Brianne Farley, Louanne is gearing up for a long winters rest by making herself doughnuts. Throughout the book she keeps getting visitors and is initially delighted to share, but batch after batch she neglects to set aside any doughnuts for herself! Eventually she runs out of ingredients, and loses it. When I read this story in the library to students we keep a running tally of how many doughnuts she's made and talk about how she could have divided that batch differently (the first visitor gets a share of every single batch!)

If I were in the classroom, I would extend the lesson by using manipulatives (like the round counters) and have the students work with partners to divide the "batches." During this group wok time I would cruise the room to make sure everyone understood the story and its application in the activity.
